Hideo Kojima has revealed a few more details about Metal Gear Solid 4: Guns of the Patriots in an interview with Game Informer. The plot forces Snake to blend in with two sides of a war while avoiding the start of conflict.
“If, for example, Snake’s mission’s goal was in the battlefield of A vs. B, Snake has the option to interfere in the battle or not,” Kojima explained. “To complete a mission, the simplest way will be to sneak into the battlefield without getting noticed by either A or B. However, if he is attacked by Country A, and kills a Country A trooper, that means he becomes an enemy of Country A. So if he continues to fight Country A, that makes him an ally of Country B, and that makes him a hero from a Country B side point of view.”
Interesting, huh? But what is even more interesting is the reason Kojima decided to continue being so involved with the MGS series. Apparently, he began receiving a number of death threats when he mentioned that he would be less involved in the project. “We talk today as if it was a joke, but at the time, it was not a joke at all. It was serious,” Kojima stated.
